Overview of instance families - Elastic Compute Service - Alibaba Cloud Documentation Center

An Elastic Compute Service (ECS) instance is a virtual server and the smallest computing service unit in the cloud. An instance type essentially determines the hardware of the host computer used for your instance. Each instance type offers different compute and memory capabilities. This topic describes all ECS instance families available for purchase and introduces their features, specifications, and use scenarios.

ECS provides a variety of instance families for different use scenarios or application workloads. Each instance family consists of multiple instance types that each have a combination of different capacities, including CPU and memory capacities. ECS instance type defines the basic properties of an ECS instance, including CPU (CPU model and clock speed) and memory. In addition to the instance type, you must also configure the Elastic Block Storage (EBS) devices, image, and network type when you create an ECS instance.

Note

The available instance families and types vary based on regions. You can go to the ECS Instance Types Available for Each Region page to view the available instance types in each region.

Enterprise scenarios require high business stability. Alibaba Cloud ECS instance families are categorized into enterprise-level and shared instance families based on whether the instance families are suitable for enterprise scenarios. Enterprise-level instance families offer consistent performance and dedicated resources. In enterprise-level instance families, each vCPU of x86-based instance types corresponds to a hyperthread of a processor core, whereas each vCPU of ARM-based instance types corresponds to a physical processor core. For more information about the differences between enterprise-level and shared instance families, see Instance FAQ.

You can upgrade or downgrade instance types within the same instance family or across different instance families. For more information, see Instance families that support instance type changes.

For information about how to choose instance families based on scenarios, see Best practices for selecting instance types.

ECS instance families are categorized into the following categories based on their system architecture and use scenarios.

Note

Intel Ice Lake supports only remote attestation based on Intel Software Guard Extensions Data Center Attestation Primitives (Intel SGX DCAP), and does not support remote attestation based on Intel Enhanced Privacy ID (EPID). You must adapt applications before you can use the remote attestation feature. For more information about remote attestation, see Strengthen Enclave Trust with Attestation.
Intel SGX depends on host hardware. This instance family does not support hot migration.
Operations such as changing instance types and enabling economical mode may cause the host of an instance to change. Changes to the host of an instance of this instance family may cause failures to decrypt data. Proceed with caution.
By default, auto failover is disabled. You can enable it. For more information, see Modify instance maintenance attributes. Auto failover causes the host of an instance to change. Changes to the host of an instance of this instance family may cause failures to decrypt data. Proceed with caution.
When you create a security-enhanced instance, you must select a dedicated image to use the security features. For more information, see Create a security-enhanced instance.

Operations such as changing instance types and enabling economical mode may cause the host of an instance to change. Changes to the host of an instance of this instance family may cause failures to decrypt data. Proceed with caution.
By default, auto failover is disabled. You can enable it. For more information, see Modify instance maintenance attributes. Auto failover causes the host of an instance to change. Changes to the host of an instance of this instance family may cause failures to decrypt data. Proceed with caution.
When you create a security-enhanced instance, you must select a dedicated image to use the security features. For more information, see Create a security-enhanced instance.

re6p, persistent memory-optimized instance family

For answers to commonly asked questions about persistent memory-optimized instances, see Instance FAQ.

Features:

This instance family uses Intel^® Optane^TM persistent memory.
Important
The reliability of data stored in persistent memory depends on the reliability of persistent memory devices and the physical servers to which these devices are attached. This increases the risks of single points of failure (SPOFs). To ensure the reliability of application data, we recommend that you implement data redundancy at the application layer and use cloud disks for long-term data storage.
This instance family allows persistent memory to be used as memory or as local SSDs on instances of some instance types.
Note
For more information, see Configure the usage mode of persistent memory.
This instance family provides the ecs.re6p-redis.<nx>large instance types for Redis applications.
Note
ecs.re6p-redis.<nx>large instance types are exclusively provided for Redis applications. Persistent memory on instances of these instance types is used as memory by default and cannot be re-configured as local SSDs. For information about how to deploy a Redis application, see Deploy Redis on persistent memory-optimized instances.

- Uses 2.5 GHz Intel^® Xeon^® Platinum 8269CY (Cascade Lake) processors that deliver a turbo frequency of 3.2 GHz for consistent computing performance.
Storage:
- Is an instance family in which all instances are I/O optimized.
- Supports ESSDs, ESSD AutoPL disks, standard SSDs, and ultra disks.
Network:
- Supports IPv6.

hfr6, memory-optimized instance family with high clock speeds

Features

This instance family offloads a large number of virtualization features to dedicated hardware with the use of the SHENLONG architecture to provide predictable and consistent ultra-high performance and reduce virtualization overheads.
Compute:
- Offers a CPU-to-memory ratio of 1:8.
- Uses 3.1 GHz Intel^® Xeon^® Platinum 8269CY (Cascade Lake) processors that deliver a turbo frequency of 3.5 GHz for consistent computing performance.
  Note
  The processors used by this instance family have a clock speed of 3.1 GHz. However, the Intel System Studio (ISS) feature may cause a lower clock speed to be displayed. Alibaba Cloud is working on this issue. This issue does not affect the actual clock speeds of your instances.
  You can separately run the following commands to use the turbostat tool to view the actual clock speeds:
  yum install kernel-tools
  turbostat
- Allows you to enable or disable Hyper-Threading.
  Note
  By default, Hyper-Threading is enabled for ECS instances. For more information, see Specify and view CPU options.
Storage:
- Is an instance family in which all instances are I/O optimized.
- Supports ESSDs, ESSD AutoPL disks, standard SSDs, and ultra disks.
- Provides high storage I/O performance based on large computing capacity.
  Note
  For more information about the storage I/O performance of the next-generation enterprise-level instance families, see Storage I/O performance.
Network:
- Supports IPv6.
- Provides ultra-high packet forwarding rates.
- Provides high network performance based on large computing capacity.
Supported scenarios:
- Scenarios where large volumes of packets are received and transmitted, such as on-screen video comments and telecom data forwarding
